microtubule-tubular rods used in mitosis and cellulose orientation in cell walls

structure of starch v cellulose

starch - up cellulose- down
flipped glucose molecules
we can't eat cellulose bc we have no enzymes to break it down

base pairing of nucleic acids

DNA

RNA

AT
GC

AU
GC

gene

protein

enzyme

g-length of DNA
p-polymer or chain of amino acids
e-protein that acts as a metabolic catalyst(workers canonly do 1 simple task)

sequence of amino acids determines

shape. sequence of nucleotides in DNA determines sequence of necleotides in RNA and determines the sequence of amino acids in protein which determines what kind of enzyme it is(what kind of work it does)
